Linking UnitTestRunner/Release on MacOS fails with Xcode

[reuk]

Sounds like this:

LLVM ERROR: SmallVector unable to grow

Anyone ever seen this error? I’m seeing it on the linking step of release builds for a product. Feels like an end of world moment LLVM ERROR: SmallVector unable to grow. Requested capacity (4294967296) is larger than maximum value for size type (4294967295) clang: error: unable to execute command: Abort trap: 6 clang: error: linker command failed due to signal (use -v to see invocation) Command Ld failed with a nonzero exit code
